In this article we will be learning how to root Samsung Galaxy S3 I9305 running on Android 4.1.2 Jelly Bean XXBMA5 firmware. Whenever you update your rooted phone with an official firmware, you lose the root access to your phone. Rooting the phone unlocks a number of features of your phone along with the ability to install custom ROMs. Although, rooting will void warranty of your device so make sure you are rooting your phone at your own risk.

Download the above packages from the links but make sure you do not extract the firmware package.

Run ODIN in your PC.

Restart the phone in download mode. To enter download mode just hold the volume down and home button and switch on using the power button at the same time. You shall see the Android Construction Logo once you enter the download mode.

Connect the phone to the PC via USB cable in this mode.

Now click on the PDA box and insert the “CF-Auto-Root-m3-m3zh-gti9305.tar.md5” file.

Also click on the checkboxes of Auto Reboot and F.Reset Time options.

Check once if all the above steps have been performed properly.

Click the Start button to star the flashing process.

After the installation is complete, your Galaxy S3 I9305 will restart and you will have a rooted Galaxy S3 for use. So have fun and do try out the custom ROMs available for your phone. If you do have any problems while installing then comment below.
